The objective of the present study is to investigate numerically the effects of thermal and buoyancy forces on both upward flow (UF) and downward flow (DF) of air in a vertical parallel‐plates channel. The plates are wetted by a thin liquid water film and maintained at a constant temperature lower than that of the air entering the channel.

The solution of the elliptical PDE modeling the flow field is based on the finite volume method.

Results show that buoyancy forces have an important effect on heat and mass transfers. Cases with evaporation and condensation have been investigated for both UF and DF. It has been established that the heat transfer associated with these phase changes (i.e. latent heat transfer) may be more or less important compared with sensible heat transfer. The importance of these transfers depends on the temperature and humidity conditions. On the other hand, flow reversal has been predicted for an UF with a relatively high temperature difference between the incoming air and the walls.

Contrary to most studies in channel heat and mass transfer with phase change, the mathematical model considers the full elliptical Navier‐Stokes equations. This allows one to compute situations of flow reversal.

The majority of the literature on green buildings in Ghana focuses on environmental benefits, innovative designs, construction technologies and project management techniques. However, little is known about how such facilities are financed. This issue creates potential knowledge gaps, one of which this study aims to address. This study examines the key drivers for green building project financing in Ghana.

The study uses an explanatory sequential design with an initial quantitative instrument phase, followed by a qualitative data collection phase. An extensive critical comparative review of the literature resulted in the identification of eight potential drivers. One hundred and twenty-seven questionnaire responses based upon these drivers from the Ghanaian construction industry were received. Data were coded with SPSS v22, analysed descriptively (mean, standard deviation and standard error) and via inferential analysis (One Way ANOVA and One-Sample t-Test). These data were then validated through semi-structured interviews with ten industry professionals within the Ghana Green Building Council. Data obtained from the semi-structured validation interviews were analysed through the side-by-side comparison of the qualitative data with the quantitative data.

Though all eight drivers are important, the five key drivers for the Ghanian construction industry were identified as, in order of importance, “high return on investment”, “emerging business opportunity”, “ethical investment”, “conservation of resources” and “mandatory regulations, standards, and policies”. The interviewees agreed to and confirmed the importance of these identified drivers for green building project financing from validating the survey's key findings.

Key limitations of this study are the restrictions regarding the geographical location of the collected data (i.e. Kumasi and Accra); timing of the study and sample size (i.e. the COVID-19 pandemic making it difficult to obtain adequate data).

Though this study was conducted in Ghana, its implications could be useful to researchers, policymakers, stakeholders and practitioners in wider sub-Saharan Africa. For instance, financial institutions can invest in green buildings to expand their green construction and mortgage finance products to build higher value and lower risk portfolios. The findings from this study can provide investors with the enhanced certainty needed to help guide and inform their investment decisions, i.e. what to invest in, and when, by how much and how a scheme being “green” may influence their rate of return. Also, for building developers, it will give them a clearer understanding of the business case for green buildings and how to differentiate themselves in the market to grow their businesses.

This study's findings provide insights into an under-investigated topic in Ghana and offer new and additional information and insights to the current state-of-the-art on the factors that drive green building project financing.

This paper aims to identify the antecedents of giving charitable donations (Sadaqah) during the pandemic in a majority-Muslim country. This paper proposes and tests a theoretical framework in which attitude toward giving donations mediates the effects of perceived behavioral control, subjective norms and past behavior on giving charitable donations (Sadaqah). The authors also investigate the mediating effect of attitude toward giving donations and the moderating effect of Islamic religiosity in an emerging nation characterized by the dominance of the Islamic doctrine. Gender, age and income have been examined as control variables.

Survey data from a sample of 377 respondents from Morocco were analyzed to test the hypotheses using structural equation modeling.

The results indicate that past behavior, subjective norms, attitude toward giving donations and intention to donate are key predictors of giving charitable donation during the COVID-19 pandemic. This paper also confirms the mediating effect of attitude toward giving donations, e.g. subjective norms trigger positive attitude toward giving donations, which increases respondents’ donation frequency. The results also suggest a significant moderating effect of Islamic religiosity, e.g. individuals who feel themselves as highly religious are more likely to develop a favorable attitude toward giving donations and are therefore more likely to donate during the pandemic.

The findings suggest practical and social implications for both academics and practitioners. As attitude, subjective norm, past behavior and intention are found to significantly influence giving charitable donations (Sadaqah), fundraising organizations should give serious attention on these factors to improve individuals’ charitable giving (Sadaqah). Such organizations should also consider the use of faith-based messages and religious morals when planning their advertising campaigns in majority-Muslim markets.

Although preliminary studies have already attempted to provide knowledge about the factors influencing giving donations among both Muslims and nonMuslims, potential antecedents of giving donations (Sadaqah) during the COVID-19 pandemic have not been considered and are yet to be empirically investigated. This paper provides new perceptions on factors influencing giving donations on a majority-Muslim majority country where no zakat institution operates. Such findings can be useful for both academicians, fundraising organizations and policymakers in Morocco to promote charitable actions and boost its socio-economic affects.

This study aims to present a framework for evaluating Green Lean (GL) maturity within organizations, focusing on the pharmaceutical sector in the Gulf region. It explores how combining Green and Lean practices can address sustainability challenges and enhance overall company performance.

A literature review was conducted to analyze the strengths and limitations of existing approaches for evaluating GL. The best-worst method (BWM) was employed as a framework for multi-criteria decision-making. The proposed tool was implemented in a pharmaceutical manufacturing company to validate its effectiveness.

The assessment model provides practical guidelines and operational conditions for organizations seeking to adopt GL practices. The study’s outcomes enable pharmaceutical companies to initiate GL strategies, contributing to sustainability and overall performance improvements.

This study has both theoretical and practical implications. It has found out the most important lean and green tools to assess and enhance enterprise performance. Therefore, this finding will strengthen the knowledge of successful implementation of GL and will further enrich the existing literature in the context of pharmaceutical industries. Moreover, this finding will also help the decision-makers in preparing an effective plan for successful implementation of GL.

This research introduces an innovative framework tailored to the pharmaceutical sector in the Gulf region. It bridges the gap between theoretical approaches and practical applications, offering a structured methodology to support sustainable initiatives in Lean practices.

This paper aims to investigate the effect of spiritual intelligence on the quality of work life (QWL) of college teachers. Besides this, the mediating impact of psychological capital on improving their QWL and moderating effect of gender has also been examined in the study.

Variance-based structural equation modelling is used for testing the proposed structural model with a sample of 451 college teachers.

The findings of the study reveal that QWL is positively influenced by spiritual intelligence. Moreover, QWL can be augmented with the presence of psychological capital. Nevertheless, there exist no gender differences with respect to the relationships of the study.

The study holds implications for the teachers and educational institutions as they can prepare themselves to cope up with the stressful events and experience a good QWL.

A teacher’s role is said to be instrumental in bringing about a holistic development in pupil’s personality by instilling right value system in him/her. Nevertheless, such role of the teachers can only be justified if the teachers are equipped with higher levels of spiritual intelligence and are psychologically more active and satisfied with their work life.

To the best of the authors’ knowledge, this study is the first of its kind that makes an incremental contribution to the QWL literature by exploring a partial mediating role of psychological capital on the relationship between spiritual intelligence and QWL.

Students’ academic achievement is a multifaceted phenomenon. While depression can suppress academic performance, academic satisfaction can promote it. This study aims to investigate the relationship between depression and academic satisfaction among students studying at Shahroud University of Medical Sciences.

This cross-sectional study was carried out on 312 undergraduate students of Shahroud University of Medical Sciences. Data collection tools included demographic data form, University Student Depression Inventory and academic satisfaction scale. Data were collected by a simple random sampling method and self-reporting by the participants. Data were analyzed using descriptive and inferential statistics (multivariate multiple regression analysis and multivariate linear regression).

The participants’ mean depression and academic satisfaction scores were 71.92 ± 22.94 and 53.70 ± 9.69, respectively. In addition, the depression score was significantly and inversely correlated with students' academic satisfaction (r = −0.122, p-value = 0.031). Moreover, there was a significant correlation between students’ depression with marital status, level of the semester, interest in the field of study and study topic.

This study emphasizes improving education, spiritual and social support and strengthens strategies to deal with depression and medical science students’ related factors.

Students of medical sciences are exposed to depression during their college years, which is related to their academic satisfaction.

This paper aims to examine the dynamic relationship among energy efficiency, health expenditure and economic growth in Malaysia over the sample period of 1980–2016.

This study uses autoregressive distributed lag cointegration analysis and the causality approach by the vector error correction model to analyse the relationship among energy efficiency, which is proxied by energy intensity and the determinant factors.

The findings of this paper suggest long-run cointegration causal links between economic growth and health expenditure. However, a mixed conclusion for both determinants exists: an increase in real income contributes to more efficient use of energy sources, whereas an increase in government spending on health intensifies energy usage.

Most previous relevant research has focussed on energy efficiency as measured by economic intensity and economic growth and do not relate to the issue of health expenditure. The recent health catastrophe brought on by the COVID-19 epidemic emphasises the significance of allocating more resources to health care. The findings will be helpful in the development of energy efficiency and economic policies in pursuit of sustainable development goals.

The paper aims to decipher, through intertwined external and internal perspectives, how female and male owners of family businesses (FB) that have been affected by the pandemic develop new capabilities to respond to the market's crisis-related needs. Specifically, this study seeks to decipher the role of external support, mediated by the owner's psychological capital (i.e. internal perspective) and moderated by gender, on the development of capabilities related to the market's changing needs, drawing on the dynamic capabilities conceptualization.

A sample of responses from 261 Canadian FB owners was generated during the pandemic, and online questionnaires were distributed.

Regression analyses and Hayes' PROCESS tool revealed that while external support directly invigorates capability development, external support is also mediated by psychological capital and moderated by gender, so that female owners were found less likely to use external support for capability development than men. These findings are explained by women's traditional responsibility in FB of protecting the family from external circumstances. Nevertheless, both women and men orchestrated external support, due to the higher psychological capital of FB, to develop capabilities that respond to pandemic-related market needs.

This study explores and demonstrates the unique navigation of FB owners during crises, and the role of the owner's gender in pursuing capability development. The study's value is in interconnecting external and internal perspectives while probing FB during crises. Implications for the ecosystem's conduct toward FB are discussed.

After completion of the case study, students will be able to examine the financial implications of Maghreb Steel’s substantial investment in the Blad Assolb complex in 2007 within the restructuring plan; explore how this decision influenced the company’s financial health and strategic position in the steel market, within the context of the restructuring plan; assess the impact of the 2008 economic crisis within the restructuring plan; analyze how the crisis affected the company’s pricing strategies, profitability and overall business strategy; investigate the financial and strategic consequences of the hot rolling activity initiated as a result of the Blad Assolb project within the company’s restructuring plan; and critique how this venture impacted the company’s operations, cost structure and competitiveness in the steel industry, aligned with the restructuring plan.

This case study deals with the only flat steel producer in Morocco: Maghreb Steel, the Moroccan family-owned company created in 1975 by the Sekkat family. It was a leading steel company. At the beginning, the company was specialized in the field of steel tubes, but thanks to its growth ambitions, the Sekkat family had made Maghreb Steel a major player in the Moroccan steel sector. In the same logic of development, the top management of Maghreb Steel launched in 2007 in the adventure to create the first production complex of cold rolling in Morocco – an investment that pushed Maghreb Steel to resort to a debt of more than 6bn dirhams (DH) with a consortium of six banks and would have allowed the company a huge leap in growth, except that the decision-makers of the group Sekkat could not see coming the economic crisis of 2008 causing the fall of steel prices by 62% compared to 2007. Thus, from its effective launch in 2010, the activity of hot rolling would become, for the company, a regrettable orientation. Moreover, the national market could not absorb all the production of the complex that the company called Blad Assolb. In response to this difficult situation, Maghreb Steel decided to store its goods to avoid selling at a loss. Faced with this situation of sectoral crisis and deterioration of its activity, Maghreb Steel lost its ability to honor its financial commitments with the banking consortium. From then on, the company became a case of failure, and the recovery measures had not ceased to be duplicated by the various stakeholders: State, Sekkat family, creditors and management of the company, having only one objective in mind: Save Maghreb Steel! This said, the present case study is dedicated to the financial and strategic analysis of the current situation and the evolution of the company throughout the crisis period to finally propose a suitable recovery plan to save Maghreb Steel.

The case study can be taught to students of master’s degrees in financial management as a synthesis of finance courses. It can also be used to train executives and managers working in family businesses as part of professional certification training.

The aim of this study is to explore and elucidate the influence of polygamy on the succession dynamics of family businesses in the Arab world, offering insights that may be underrepresented or overlooked in traditional, Western-focused literature.

This article adopts a perspective-based approach, focusing on delving into the amalgamation of polygamous family structures and their implications on the operation and continuation of family-run businesses.

Polygamy, while often primarily perceived as a cultural or religious tradition, wields substantial influence over various business facets. Notably, its presence can significantly shape business continuity, the methodologies behind succession planning and the overarching framework of corporate governance within Arab family businesses.

This article offers a unique Middle Eastern lens, highlighting the underexplored intersection of polygamy and business succession. It strives to bridge the knowledge gap by addressing topics potentially sidelined in mainstream Western business research.
